install

First you should install blender and find the path to the blender executable.

<path_to_blender>/2.93/python/bin/python3.9 -m ensurepip --upgrade
<path_to_blender>/2.93/python/bin/python3.9 -m pip install PyYaml ipdb opencv-python tqdm
# For example, in my MacOS:
/Applications/Blender.app/Contents/Resources/2.82/python/bin/python3.7m -m ensurepip --upgrade
/Applications/Blender.app/Contents/Resources/2.82/python/bin/python3.7m setup.py develop
/Applications/Blender.app/Contents/Resources/2.82/python/bin/python3.7m -m pip install PyYaml ipdb opencv-python tqdm

And clone this repo and install it:

git clone https://github.com/chingswy/BlenderFig.git
cd BlenderFig
<path_to_blender>/2.93/python/bin/python3.9 setup.py develop
